COLLECTING GAS FROM FERVIENTING LIQUORS.

SPECIFICATION forming part of Letters Patent No. 604,125, dated May 17,1898.

Application filed September 2, 1897. Serial No. 650,337. (No model.)

`To all whom it may concern-.-

Be it known that I, JOSEPH SCHNEIBLE, a citizen ofthe United States, anda resident of the city, county, and State of New York,

5 have invented certain new and useful Improvements in the Collection.of the Gas of Fermenting Liquors, of which the following is a full,clear, and exact specification, reference being had to the accompanyingdrawings, which form a part thereof.

This invention relates to the collection of carbonio-acid gas as thesame is given off or generated during the fermentation of liquids, suchas malt liquors, with a view to the use of the gas subsequently, eitherin the further treatment of the liquors or for other purposes.

The objects in view have been particularly to avoid the necessity ofusing a gasometer, through which the entire volume of the gas collectedordinarily passes; to avoid the necessity of provision for storage ofthe gas, either compressed or uncompressed; to make the requisiteapparatus as simple and inexpensive as possible and to render itsoperation automatic, and at the same time to avoid any interference withthe conditions, particularly as to the pressure thereon, which have beenpredetermined for the fermentation of the liquid in question. l

In the practice of the invention the desire results are made possiblelargely by delivering the gas from the fermenting vessels directly to acompressor and byv causing the pressure on the supply of gas (whetherthe same is above or below the atmospheric pressure) to regulate thecompressor automatically, so that the compression of the gas keeps paceexactly with the generation. From the compressor the gas may beconducted directly to the place of use or may be introduced intosuitable receptacles for shipment,

'or may be otherwise handled or disposed of,

as may be required or preferred.

For purposes of explanation of the nature of the invention a convenientand practical form of apparatus has been chosen for illustration in thedrawings of one embodiment of the invention.

In said drawings, Figure l is a general view showing fermenting vesselsin connection with the compressor and regulating devices, other devicesfor the further treatment of the gas being also indicated, Fig. 2 is adetailed plan View of the governor or regulator and a portion of thecompressor. Fig. 3 is a detailed View of the governor or regulator,partly in elevation and partly in vertical section. Figs. l and 5 aredetailed views showing parts of the governor or regulator. Fig. 6 is adetailed view in section of a valve for controlling the action of thecompressor.

In the embodiment of the invention represented in the drawings closedfermenting vats or vessels of ordinary construction are represented at AA, a compressor, also of ordinary construction and needing no detaileddescription herein, at B, and a governor at C, the latter beingpreferably constructed to operate in substantially the manner more fullydescribed hereinafter. A collector for the gas generated in eachfermenting Vessel is formed conveniently by the closed top of suchvessel, and the collector or several collectors are connected directlyto the compressor B by a suitable pipe-line, (indicated at a.) A branchpipe c from any convenient point serves to ltransmit the pressure of thesupply-that is to say, of the gas as it is generated*to the governor,the last mentioned pipe being preferably connected to the main pipe andthe system of collectors at the remote end in order to provide aconvenient means for steaming out the pi pe system whenever required.

The compressor represented in the drawings is an ordinary direct-actingsteam-compressor, the gas being delivered to the compression-cylindersby the pipe a and conducted therefrom by a pipe b, while the steam isdelivered to the steam-cylinders by a supplypipe b'. The pipe b deliversthe gas wherever required, and there is shown in the drawings asinterposed in this pipe a washer D, the latter being operated byasuitable pump E. A pressure-regulator F is also represented as connectedto the pipe Z).

The governor shown in the drawings is so constructed as to be readilyresponsive to variations in the pressure of the gas-supply, whether suchpressure be above or below the atmospheric pressure, and is alsooperatively related to the compressor, so as to control the latter andto make the compression of the gas keep pace exactly with the supply,thereby IOO avoiding variations of pressure on the fermenting liquors.The compressor illustrated comprises a tank G', having a supplementalchamber C2, with which it is connected at the bottom by relatively smallapertures c. The tank and the supplemental chamber are filled with anysuitable liquid, and in the tank is placed a iioat C3, which is soconnected with the valve G, which controls the admission of steam to thesteam-cylinders of the compressor, as to open or close the same more orless, according to the quantity of gas generated,the branch orpressure-transmittin g pipe a being connected to the upper part of theclosed supplemental chamber C2 to transmit the pressure of thegas-supply to the surface of the liquid therein, and thereby to causethe float C3 to rise or fall as the pressure increases or diminishes. Itis obvious that the connection between the float C3 and the movable partof the valve G may be arranged in many diiferent ways to accomplish thedesired purpose. In the construction represented in the drawings thevalve-plug G is mounted to rotate in its seat Ggand is provided withports g to register with corresponding ports g2 in the seat, the plugbeing hollow to permit the passage of the steam to the steam-cylinders.The plug is further provided with a suitable stem g, which projectsthrough a suitable packing-box in the valve-casing. The float isrepresented as counterbalanced by means of a Weight c' and weight-beamc2, to one end of which the float is connected by a suitable stem c3.The beam is pivoted upon a suitable support c4 and is connected tothevalveplug G', so as to cause the latter to oscillate as the float risesand falls. To facilitate the setting of the parts, a simpleexpansionjoint c5 may be connected by a universal joint c6 at one end toa rod c7, which is secured to the beam c2, in line with the pivotal aXisthereof, and by a universal joint c8 at the other end to a dog e9, whichis secured to the stem g of the valve-plug G.

In order that the variations of pressure of the gas-supply may beobservable at all times, a double-sight tube is connected to thegovernor, one member H being connected at its lower end to thesupplemental chamber C'/2 and at its upper end to the atmosphere, sothat the liquid therein will stand at the same level as the liquid inthe main tank, while the other member I-I is connected at its lower endto the supplemental chamber and at its upper end also to saidsupplemental chamber, so that the liquid therein shall stand at the samelevel as the liquid in the supplemental chamber, which is subjected tothe pressure of the gas-supply, whereby the difference in height of thetwo columns of liquid will represent the pressure of the gas-supply.

It is obvious that various changes may be made in the mechanical detailsof the apparatus employed without departing from the invent-ion, whichcontemplates the delivery of the gas as generated directly to acompressor and the automatic regulation of such compressor by thepressure of the gas-supply, so that the compression shall proceed at thesame rate as the generation of the gas. Therefore it is to be understoodthat the invention is not limited to the precise construction andarrangement of parts shown and described herein.

I claim as my inventionl. An apparatus for collecting the gas offermentation comprising a collector, a compressor connected directly tothe collector, a governor subject tothe varying pressure of thegas-supply and means actuated by said governor to control thecompressor.

2. An apparatus for collecting the gas of fermentation comprising acollector, a compressor, a pipe to deliver gas from the collector to thecompressor, a governor, subject to the varying pressure of thegas-supply and connected with the collector by a branch pipe and meansactuated by said governor to control the compressor.

3. An apparatus for collecting the gas of fermentation comprising acollector, a compressor connected directly to the collector, a governorcomprising a closed chamber and a iioat, a pipe connection between saidclosed chamber and the collector and means actuated by said oat tocontrol the compressor.
